[0025] See also Figure 3-Figure 4In this embodiment, the positioning assembly includes a bidirectional threaded rod 201, a first slider 202, a first drive motor 203, a support column 204, a rotating shaft 205, a second drive motor 206, a limit frame 207, a splint 208, an adjusting bolt 209 and an anti-slip pad 210. The surface of the bidirectional threaded rod 201 is arranged to be opposite to each other and is provided with two groups of first sliders 202 for sliding. The first drive motor 203 drives the bidirectional threaded rod 201 to rotate and drives the two groups of first sliders 202 to slide relative to each other along its surface. By setting the first drive motor 203 to drive the bidirectional threaded rod 201 to drive the first slider 202 to slide relative to each other along its surface, the spacing between the two groups of splints 208 can be adjusted to adapt to cylinder rollers of different widths.

By setting the anti-slip pad 210 to increase friction, the clamping effect can be better.

[0026] See also Figure 5-Figure 6In this embodiment, the welding assembly includes a one-way threaded rod 301, a second slider 302, a third drive motor 303, a telescopic cylinder 304, an electric push rod 305, a cross bar 306, a welding module 307, a welding head 308, an infrared sensor 309 and a lighting lamp 310. The one-way threaded rod 301 is symmetrically provided with two groups. The surfaces of the two groups of one-way threaded rods 301 are both provided with a second slider 302 for sliding. The third drive motor 303 drives the one-way threaded rod 301 to rotate and drives the second slider 302 to slide along its surface. By setting the third drive motor 303 to drive the one-way threaded rod 301 to drive the second slider 302 to slide along its surface, the position of the welding module 307 can be adjusted so that it can complete the scanning and repair of different parts of the cylinder roller. The upper end of the second slider 302 is fixedly installed with a The telescopic cylinder 304 controls the up and down movement of the electric push rod 305. The upper ends of the two groups of electric push rods 305 are relatively arranged and fixedly connected with a cross bar 306. A welding module 307 is fixedly installed between the two groups of cross bars 306.

By setting the lighting lamp 310, it can brighten the light when the light is poor, thereby ensuring the accuracy of the infrared sensor 309 scanning.

[0027] When working, first move the workbench 1 to the corresponding position so that the legs 6 can provide a stable support for the workbench 1;

[0028] Then, the switch of the relevant structure is turned on through the control panel 7, the cylinder roller is clamped and fixed using the positioning assembly, and the bidirectional threaded rod 201 is driven to rotate by the first drive motor 203, so that the two sets of first sliders 202 on the surface of the bidirectional threaded rod 201 slide relative to each other until the distance between the two sets of clamping plates 208 is adjusted to a suitable size;

[0029] Next, place the connecting shafts 5 at the left and right ends of the roller body 4 on the limiting frames 207, and tighten the adjusting bolts 209 to control the clamping plates 208 to move downward until the clamping plates 208 and the anti-slip pads 210 on the inner side of the limiting frames 207 are tightly attached to the surface of the connecting shafts 5, so that the clamping plates 208 cooperate with the limiting frames 207 to clamp and fix the connecting shafts 5;

[0030] The surface of the cylinder roller is then scanned and repaired by welding using the welding assembly. The third drive motor 303 drives the one-way threaded rod 301 to rotate, causing the one-way threaded rod 301 to drive the second slider 302 on its surface to slide left and right. This causes the infrared sensor 309 to scan and sense defects on the cylinder roller surface, and the welding head 308 simultaneously performs welding repairs on the detected defects.

[0031] During the process of welding and repairing the cylinder roller surface by the welding assembly, the second drive motor 206 drives the rotating shaft 205 to drive the cylinder roller to rotate, so that the roller body 4 cooperates with the welding assembly by rotating until all defects on the surface of the roller body 4 are repaired.

[0032] Through the above steps, by setting an adjustable positioning component, cylinder rollers of different sizes can be clamped and fixed, which is more adaptable. By setting a driving structure that can drive the cylinder roller to rotate on the positioning component, the cylinder roller can be controlled to automatically adjust its position to adapt to the welding module 307, which is faster and more efficient. By setting an infrared sensor 309 on the welding component, the defects on the surface of the cylinder roller can be automatically scanned and sensed to cooperate with the welding head 308 to repair the surface of the cylinder roller, thereby making the repair accuracy higher and the repair effect better, so as to solve the problem that the existing cylinder roller welding repair equipment usually has a positioning structure that can only be used to fix cylinder rollers of fixed sizes, and in the process of welding and repairing the cylinder roller, manual cooperation is required to adjust the position of the cylinder roller to complete the repair of different parts. The operation is relatively cumbersome, laborious and labor-intensive, and the accuracy is not high, resulting in low work efficiency.
